Solution Overview

Problem

Conventional BER measurement apparatuses require manual connection of multiple signal terminals, which is time-consuming and prone to errors, and cannot perform measurements if predefined signals are not supplied to corresponding input terminals.

Innovation Solution

An automatic signal detection apparatus that includes input means for receiving at least two signals, detection means to identify the type of signals, and a selector to output the detected signals to their respective terminals, allowing for automatic identification and routing of clock, data, sync, and validity signals.

AI summary

An apparatus comprises input means, detection means and a selector, and automatically detects a kind of serial signal used in BER measurement. The input means receives at least two signals which include a data signal, and a clock signal having a period corresponding to one bit of the data signal. The detection means determines which one of the at least two signals is a clock signal or a data signal. The selector outputs the signal determined to be a clock signal from a clock signal terminal and outputs the signal determined to be a data signal from a data signal terminal.
